Exercising Harder—and Shorter—Can Help Type 2 DiabetesReleased December 12, 2011
- Regular exercise has proven benefits in preventing and treating type 2 diabetes, but many patients find it tough to meet the American Diabetes Association guidelines of 150 minutes of moderate to vigorous exercise a week. A new study suggests that there could be a better way. In a small proof-of-principle study in eight type 2 diabetes patients, the researchers found that exercising at a very high intensity, but for a mere 30 minutes a week within a 75 minute total time commitment, lowered overall blood sugar concentrations, reduced post-meal blood sugar spikes, and increased skeletal mitochondrial capacity, a marker of metabolic health. The findings suggest that exercising harder, but in a significantly shorter amount of time, could provide benefits similar to longer, but more moderate, activity.
